Liquid scintillator based experiments in neutrinoless double beta decay

Recent experiments have confirmed neutrino oscillations. The mass structure of neutrinos is one of the next interesting subjects in neutrino physics. Neutrinoless double beta decay has the potential to investigate the mass structure of neutrinos. Many neutrinoless double beta decay experiments are being proposed and some were introduced at this conference. Here we present neutrinoless double beta decay experiments based on liquid scintillator techniques. SNO+ plans to use ¹⁵⁰Nd as the neutrinoless double beta decay isotope dissolved in liquid scintillator, similarly KamLAND-Zen will use ¹³⁶Xe loaded liquid scintillator. The physics goals, schedule and current status of both experiments were discussed.
